La zona rossa
No full textUna video lezione di scienza adatta ad un giovane pubblico ed incentrata sul tema del confinamento in emergenza sanitaria da COVID 19. Gli autori, spiegano mediate un dibattito tra una ricercatrice ed il nuovo coronavirus, cos’è una zona rossa. I protagonisti paragonano una zona rossa ad un orto infestato da un vorace insetto, spiegando come l’isolamento dell’orto sia necessario affinché i raccolti degli orti vicini rimangano salubri. Gli autori attraverso tale similitudine mettono in evidenza come l’isolamento delle città sia l’unico modo per ridurre la diffusione del virus e come tali provvedimenti possano rendere disponibili tutti quegli ausili sanitari come anche le energie del personale coinvolto in prima linea nella lotta all’emergenza sanitaria causata dal Covid-19
The international cooperation between the Egyptian Ministry of Antiquities and the University of Milan for the excavation and preservation of an endangered site in Aswan
Get PDFThe Egyptian Ministry of Antiquities and the University of Milan collaborate in the protection, preservation and valorisation of the large necropolis surrounding the Mausoleum of the Aga Khan in West Aswan. The first mission has been completed, the second is underway. Director Patrizia Piacentini describes the work and finds from the first mission and the experts from different fields (anthropology, palaeopathology, chemistry, botany, restauration, the computer sciences) that will be deployed during the second phase. Particular emphasis has been given to the historical meaning of the necropolis, in general, and, in particular, of tomb AGH026, which was excavated in 2019. They promise to yield information on the history and international contacts of the population of Aswan during the Late Pharaonic and Ptolemaic-Roman Period. Vicedirector Massimiliana Pozzi Battaglia enumerates some of the particular issues that were encountered from the point of view of conservation and transport. Inside Tomb AGH 026 different conditions were encountered, depending mostly on whether sand had covered a specific spot or not, which conditioned the preservation of the human bodies, cartonnage-making and wooden items and influenced their transportation and storage. Said Mahmoud Abd El-Moneim, General Director of Aswan and Nubia Antiquities Zone and Co-director of the mission at Aga Khan necropolis, widens the scope of the article to address other endangered sites that at present concerns of the Egyptian Ministry of Antiquities. He describes the challenge posed by raising water levels and increased quarrying activity at Kom Ombo, Philae and Bigga, the rock art and palaeolake sites in the Aswan area
Logic and computing: a historical background
Get PDFThe history of archaeological computing has long been characterised by the distinction between the application of mathematical and statistical techniques, as part of the so-called movement of quantitative archaeology, and the use of databases and information systems for descriptive and documentary purposes. The intensity of the debate on the relationship between logic and computing, as well as between theory and applications, began to wave in the 1990s. Over time, data integration and new ICT tools have allowed archaeologists to address simultaneously all the issues raised by the archaeological research. This paper focuses on the evolution of methods and techniques in this specific research area, thanks to the analysis of literary sources, the Bibliography of Archaeological Computing, accessible via the Virtual Museum of Archaeological Computing website, and the scientific articles published in the open access international journal Archeologia e Calcolatori
Qualitative and quantitative approaches in digital epigraphy
Get PDFAn epigraph is a complex historical document, whose significance is fully acknowledged only if its textual features (script, language, content, etc.) are studied in combination with the contextual information (on the textual support and its provenance). This is the reason why digital epigraphy lies at the crossroads of different disciplines applying ITs to textual and material sources, such as digital philology, computational linguistics, and computational archaeology. The specific interests and methods of those disciplines have exerted an influence on digital epigraphy, which is apparent in the documentary vs statistical approaches applied over time to the electronic treatment of the (re)source ‘inscription’. The aim of the paper is to trace those trends in the application of qualitative vs quantitative methods in the history of studies of digital epigraphy, highlighting the main moments of change, until the most recent developments
Structural monitoring of the Ninfeo Ponari by fibre optic sensors, photogrammetry and laser scanning
Get PDFThe Ninfeo Ponari is an ancient building dating back to the first century BC as part of a rich domus, located in the ancient Roman city of Casinum. It consists of two bodies: a rectangular room covered by a barrel vault and an atrium with no roof with a shallow pool in the middle, both paved with mosaics and decorated with wall paintings. The structural condition of the building is critical and its preservation is at risk, as it is located on a hill slope where some substantial sliding activity is occurring. Moreover, it is not protected by an efficient rainfall drainage system. Aim of this paper is to illustrate the strategies and the digital techniques recently applied to initiate a permanent monitoring of the building structural condition
Applying digital tools as an effective support for conservation research and design process: the Rocca Janula castle in Cassino, Lazio
Get PDFThe paper deals with the very extensive and complex topic of the conservation and adaptation of the medieval defensive castle of Rocca Janula in Cassino for the headquarters of the non-governmental organization Corvi di Giano. The castle is a very important building due to its location and its history. Its location makes it one of the two landmarks of the city’s landscape. Due to its connections with the Montecassino Monastery, it has a great cultural significance for Poland and Italy. The research described in this paper is an attempt to re-integrate the fortress into social life. The project is an example of the application of digital recording methods such as photogrammetry, HBIM technology and 3D printing. The integration of these methods allowed creating a database by which valorization practices were implemented and conservation guidelines were formulated
Grapevine Green Pruning Residues as a Promising and Sustainable Source of Bioactive Phenolic Compounds
Get PDFGreen pruning residues (GPRs) and leaves from 16 red and white Vitis vinifera L. cultivars from Piedmont (Italy) were studied. The investigated samples were extracted by ultrasound-assisted extraction optimized by an experimental design, and quali- and quantitatively analyzed by HPLC-PDA-MS/MS. GPRs and leaves show a similar polyphenolic pattern, with quercetin 3-O-glucuronide, caftaric acid, and quercetin 3-O-glucoside as the main components, although in variable proportions. The HPLC results were related to the antioxidant activity, measured as total phenolic content and through DPPH and ABTS assays with similar results. Colorimetric in vitro assays, offline combined with HPLC-PDA analysis, determine which compounds contribute to the antioxidant activity in terms of radical scavenging abilities. Valorization of GPRs is a potential source of natural compounds that could be of interest in the health field, increasing their economic value together with a positive effect on the environment
Self-Expandable Transcatheter Aortic Valve Frame Infolding: An Increasingly Recognized Complication
Get PDFTranscatheter aortic valve replacement (TAVR) with either a balloon-expandable or a self-expandable transcatheter heart valve (THV) is an approved therapy for patients with symptomatic severe aortic stenosis and high or intermediate surgical risk. Here we present a case of severe valve frame infolding of a CoreValve Evolut PRO® self-expandable THV (Medtronic Inc.), which was restored to optimal geometry with balloon post-dilation
